M: I am saying there is no way to know. I often have the feeling when I kill a fly, which I seldom do by the way, that I just crushed the only extant gene that would have lead to a super civilization some billion years from now. But as I pointed out, for every potential bad there is a corresponding potential good. We might be getting rid of Hitler or Jesus, no?
CW: So you concur that there is no way to know. My suggestion is that basing anything on a probability of doing good is inherently flawed. I suppose this because we do not know the probability that what we are doing is wrong, nor do we know the probability that something good can come of it. Thus, I must abide by my previous stance that we avoid doing wrong just for a chance at doing good. This is the ground that I stand on when I oppose Guantanamo Bay internment, torture, and other unjust means for the possibility of preventing future terrorist acts. If we violate the principle of justice, the outcome can never truly be considered positive.
M: But all of this is a matter of hindsight. At the point where you don't think much of your life is where it would have ended. That is the end and none of the rest would have come to be. Life is sacred to the living who are conscious of life. It means nothing to a rock or an amoeba as such but life seeks to preserve itself. Life is a profound experience for the conscious mind and a mystery the mind can't fathom.
CW: But we have the benefit of hindsight and the wisdom that comes with it. I know now that, given the choice, I would not have given my life away at this early stage of development for research purposes. Since I believe you previously agreed that the embryo simply another step inexorably forward on the continuum of human development, the interruption of that development is to willfully destroy the chance of having the human experience that the embryo will most likely have if nature were to take its course.
M: But I think the rational mind can't make a trap of that feeling. The absolute reverence for any genetic material that potentially could become human leads to illogical behavior. There are monks who sweep the path of bugs before they walk so they don't step on living things. Us 'normal' people think that's absurd. You have a similar belief if somewhat less extreme. We have walked down a road that leads to scientific manipulations of life that transcend anything our old ethical systems were prepared to handle and it's up to us to find our way in uncharted waters, I think.
CW: As I said, there is no question whether a fertilized egg is human. My question is why may we interrupt the continuum of development at some arbitrary stage. My stance is dissimilar to those monks in that I place a higher value on human life than the life of the cricket that might be trampled. Our society has become complacent in its protection of human life to the point where it is nearly disposable, where greater sympathy is attached to unborn animals than unborn humans:
"Although we are thankful that the fisherman gave this unique specimen to Mote, and we are learning a lot about this species from this large female shark, we were saddened to see so many unborn pups inside her so close to birth," said Dr. Robert Hueter, director of Mote's Center for Shark Research.

The sadness and regret expressed by Dr. Hueter are clearly due to his perhaps unconscious notion that these sharks, despite being unborn, were still sharks. They were simply at an earlier stage of development than would have allowed them to escape this untimely demise. Can we really say that, while we were saddened to see so many unborn humans consumed, we are glad that they unwillingly contributed to the betterment of the lives of others?
Perhaps my notion is that the fundamental characteristic of the human condition is choice. These humans are being deprived of any choice in this matter. The decision being made isn't exactly trivial as far as these humans are concerned. If the decision goes one way, then these humans will never be allowed to choose anything for themselves. They will simply be swallowed up into the collective on the whim of another. This Borg-esque approach in which humans are assimilated is essentially a devaluing of the human race, where one individual is considered negligible as long as society deems they may benefit from his consumption.
